Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2021/095675 filed on May 25, 2021, which claims the priority to Chinese patent application No. 202010757027.0 filed on Jul. 31, 2020 and titled “PIXEL STRUCTURE AND DISPLAY PANEL”, both of which are incorporated herein by reference in their entireties. TECHNICAL FIELD This application relates to the field of display, and particularly to a pixel structure and a display panel. BACKGROUND With a rapid development of electronic devices, users have higher and higher requirements for screen-to-body ratios, such that the industry has shown more and more interest in all-screen displays of electronic devices. There is a need for traditional electronic devices, such as mobile phones and tablets, to have front-facing cameras, earpieces, and infrared sensing components etc. integrated thereon. In the prior art, notches or holes may be provided on display screens, so that external light can enter photosensitive elements under the screens through the notches or holes on the screens. However, these electronic devices do not have actual all-screen displays, since not all regions across the screens can be used to display, for example, regions corresponding to front-facing cameras cannot be used to display pictures. SUMMARY Embodiments of the present application provide a pixel structure and a display panel, enabling at least a part of regions of the display panel to be light-transmitting and display. In one aspect, embodiments of the present application provide a pixel structure, includes: a plurality of repeating units arranged repeatedly, each of the repeating units includes a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel, wherein the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are adjacent to each other in sequence, wherein a center of the first sub-pixel and a center of the second sub-pixel are connected by an imagined first center connection line, the center of the second sub-pixel and a center of the third sub-pixel are connected by an imagined second center connection line, and the center of the third sub-pixel and a center of the fourth sub-pixel are connected by an imagined third center connection line, the imagined first center connection line and the imagined third center connection line are located on one side of the imagined second center connection line, and a minimum distance between the first sub-pixel and the fourth sub-pixel is greater than a minimum distance between the second sub-pixel and the third sub-pixel; and a light-transmitting portion located between adjacent repeating units. In another aspect, embodiments of the present application provide a display panel including the pixel structure according to any of the above implementations. According to the pixel structure of the embodiments of the present application, in each of the repeating units, the imagined first center connection line and the imagined third center connection line are located on one side of the imagined second center connection line, and the minimum distance between the first sub-pixel and the fourth sub-pixel is larger than the minimum distance between the second sub-pixel and the third sub-pixel, so that the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are arranged adjacent to each other in sequence to form a roughly C-shaped semi-surrounding structure, in which the area semi-enclosed by the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel can be used to configure the light-transmitting portion, with enough space reserved to dispose the light-transmitting portion in the pixel structure after the sub-pixels are arranged, the light transmittance of the display panel including the pixel structure can be improved. When the repeating units are arranged in a preset regularity, the light-transmitting portions between the repeating units are also distributed regularly and relatively evenly, so that the light which can be transmitted through the display panel including the pixel structure is distributed more uniformly, which is convenient to applied in light-transmitting display technology or under-screen photosensitive element integration technology.
